Please advise and offer some diagnostic help please!
I've built a PC tech specs as follows:
Onboard graphics only
AMD Catalyst Driver Version, and Driver History
Cannot install driver, video drops out
Win 8 SP1 / Ubuntu 12.04
- Standard installs and setup, base OS software and configuration
Installing AMD driver under windows 7/8 results in video dropping out. Connected to monitor with DVI-D cable. In Ubuntu, onscreen graphics is a little glitchy with unusual lines appearing across the screen randomly and occasionally. Attempt to install AMD graphics drivers for Linus results in the install freezing with just a grey box in the install screen window.

Downloaded and ran check with AMD System Monitor to see performance of core CPU's and gpu. Cores showing small percentage of throughput, however gpu running flat at 0% (this in particular makes me feel the gpu may be faulty).

No other hardware to swap out chips. Appart from video driver installation problem and Ubuntu screen glitches everything else seems to be running fine. Please advise any other suggestions you may have to pin-point the problem. If you have comparison tests in AMD System Monitor software, the 0% activity of my GPU could verify problem.
